A method of defining access control. The method allows the expression of access control rules using ontology based semantics and references an ontology subset using XPath as the ontological expression. The access control rules or access criteria are defined by an access control statement and may be expressed using classification criteria and ontology classes. The access control statement comprises a structural description that is used to define an asset and a logical expression that may be used to express the classification criteria. The access control statement defines access policy for various assets.
